3.4 Overview of Function Groups
Fig. 3-4 ES930.1 Block Diagram
The block diagram in Fig. 3-4 on page 20 displays function groups of the
ES930.1 module that are described in the following chapters:
• Power supply (see chapter 3.5 on page 21)
• ETAS daisy chain connections "IN" and "OUT" (see chapter )
• Inputs and outputs
– Thermo channels "TH1" to "TH4" (see chapter 4 on page 29)
– "DI" digital input channels (see chapter 5 on page 31)
– Analog input channels "AI 1" to "AI 8" (see chapter 6 on page 45)
– Outputs to the sensor power supply (see chapter 7 on page 49)
– "AO" analog output channels (see chapter 8 on page 51)
– "DO" digital output channels (see chapter 9 on page 53)
– "PS" Half-bridges (power stages) (see chapter 10 on page 59)
The function groups of the module are described in the following chapters.
